DUMPlN-CAR. I

Specification of Letters Patent.

Patented J an. 8, 1907 Application filed October 22, 906. s m Noi310,05b.

To all whom it malylcon cernz Be it known that I, CLIFTO EDGAR HE MAN, a citizen of-the'United States, residing at Columbus, in the countyof Franklinf and State of Ohio, have invented certain new and useful Improvementsin Dumping Cars clear, and'exact description of the invention,

like reference characters and I do declare the following to bea full,

such as will enable-others skilled in the'art to which it appertains to make and use the same.

This inventionrelates tb dumping-cars and means for operating the dumping mechan sm.

The object dumping-ear which may be quickly unloaded, which has aneans. for holding the doors securely fastened when the car is in use, and

. provided with simple means foropening and closing said doors a In the accompanymgdrawmgs, in which indicate corresponding parts, Figure .1 represents atop plan view of a car constructed in accordance with this invention, the doors forming the bottom on one side of the car being omitted. Fig. 2 represents a transverse section through the car, showingthe drop-doors at the'right side in closed position and those at the left open. Fig. 3 represents an end View of the car. Fig. 4 represents a bottomplan view of one of the middle doors. Fig. 5 represents a similar view of one of the doors which is at tached to the sides of the. car. Fig. 6 represents a perspective view of one of the folding leversdetached. Fig. 7 represents a front View of the bell-crank of one of the folding levers. Fig: 8 represents a n-xrspective view of a shaft-hanger and bearing ready for assembling. Fig. 9 represents a-detail view showing a side elevation of the operatinglever, and Fig. 10 represents a side elevation of the upper member of one of the folding levers. 5

in the embodiment of my lnvention shown in the drawings the car 1 is provided with a central partition 2, which divides the bottom of the car longitudinally into two compartments braced by suitable sills, as 3. Each compartment has an inclined bottom composed'of a plurality of doors, as 5, hinged at one edge to the central partition 2. Corres onding doors 15 are hinged to the side of t e car. Thedoors 5 are provided at their free ends with catch members 6 for engaging of the invention is to provide a pivoted complementar members 16.0n the doors 15 for holding t 0 doors 15 in closed position. ,These catch members 6 am ref-.-

erably made/from a single metal strap ent to form anflL-shaped hook with its free ends placedonthe opposite sides of the door edge and bolted thereto and with its foot 7' jecting upwardly at right :angles to the' oor edge in position to engage the pivotedmembers 16 of thedoors 15; These doors 5-are,

preferably braced on their lower faces by spaced channeled irons 8, to which the hinges and catch members maybe attached;

To-the lower faces of the. doors 5, prefer- 7 ably on the braces 8, are securedplates 9, having spaced perforated ears 9, in whichare pivotally mounted jointed levers '10. These levers '10 are each composed ofthe bar' 11, pivoted at one end between the ears 9 of the plate 9-, and the bell-crank lever 12 has :one of its arms bifurcated at .its upper end and provided with a'recess or pocket 13,

formed in one face of said arm. This bifurcated end is apertured to receive thepivot .pin 14, which also passes through an aper-. ture in the barll at a point some distance from its free end to pivotally connect said bar 11 with the arm ofthe bell-crank lever v 12, said free end resting in the socket 13 and held against inward bending by the wall of.

said socket, while permitting it to bend outward when desired.

'Shafts 20, preferably an ular in cross-section, are mounted longitu inally of the carbottom in hangers 21, secured to-the braces 3. Each car is preferably provided with four shafts 20, two-being disposed on each side and operated from opposite ends of the car. These shafts 20 have fixed on their outer ends segmental ratchet-gears 22, ada ted to be enga ed by pawls 23, pivoted to t 1e car-body for holding the shaft against rotation in one direction. Onthese shafts 20 at points below the doors 5 are fulcrumed the bell-crank levers 12, with their free arms extending toward the-sides of the car to en gage the doors 5 when disengaged from the doors 15 and .limit the downward drop of said doors 5.

On the outer terminals of the shafts 20 is adapted to be mounted a detachable operating-lcver 30, having a knuckle-joint 31,-

tion and holds it against bending in the other direction. This lever has an aperture to fit doors 15 above the notches of the car, are bracedsimilarly to thedoors and have notches 17 cut in their free edges at points opposite the catch members 6 of the doors 5 to. permit said catches 6 to pass there.

through when the doors are swung inward to close them. On the outer faces of the 17, are pivoted I gravity latches or flaps 18, which are pushed crating-lever 30 outward by the catches 6 when the doors 15 are swung in and drop by gravity over the notches 17 and close them and are engaged by the catch-hooks 6 to hold the doors 15 in closed position, i

In the use of this car when constructed as shown, the car bein ready to dump, the 015- is placed on the end of one of the shafts 20 with the knuckle of the lever at the top thereof, the pawl 23 is disengaged from the ratchet-wheel 22, and the lever is'moved in the direction of the arrow shown at the right of Fig. 8, which movement rotates the shaft 20 and bends the folding levers at their pivot and causes the doors 5 to drop down until the free ends of the arms of the bell-cranks of said folding levers engage the lower faces of the doors 5 and hold them against further downward movement. This droppin of the doors 5 disengages the catches 6 from the fiaps l8 and releases the side doors 15, which drop by gravity into the position shown at'the left of Fi 2, permitting the substance contained in .t e car to dro therethrough. When the doors 5 drop, t to shaft with the attached lever 30 revolves rapidly and causes the lever 30 to break or bend at its knuckle 31 and prevents the lever from flying up and striking the operator. When 1 the car has been unloaded and it is desired to close the doors .5 and 15, the lever 30 is rehold the doors securely together.

, folding levers moved and replaced with the knuckle on the lower side, the pawl 23 is dropped into engagement with the ratchet, and the lever is moved in the directionof the arrow at the left of Fig. 2, turning the shaft 20 until the are in normal straight position, which holds the doors 5 in closed position. The doors 15 are then pushed by hand toward the doors 5 over the edges thereof, causin the catches6 to push back the flaps 18 and pass through the notches 17. The latches then drop by gravity over said notches, and when the doors 15 are released they swing down until said catches engage the outer faces of the flaps or latches 18 and I. claim as my invention- I 1.
